Abstract
The present disclosure relates to a retrofit system (600) for stairs, comprising a support angle (602) comprising a horizontal panel (604) and a vertical panel (606). The support angle is configured for connection to the stairs. A rail (608) is disposed on the horizontal panel, and a bracket (610) is configured for coupling with a tread of the stairs and at least partially form fits over a top of the rail such that the bracket allows for sliding movement of the stairs as guided by the rail. The retrofit system for stairs as configured reduces stair damage during building movement whether it is from wind, thermal, or seismic activity, and/or any other type of suitable force or experience, as the retrofit system for stairs as configured allows for directional movement, or a combination thereof, including tension and compression, lateral, or vertical movement.
Claims (12)
1. A retrofit system for stairs, comprising: a support angle comprising a horizontal panel and a vertical panel, wherein the support angle is configured for connection to the stairs; a rail disposed on the horizontal panel; and a bracket configured for coupling with a tread of the stairs, wherein the bracket is configured to at least partially form fit over a top of the rail such that the bracket allows for sliding movement of the stairs as guided by the rail.
2. The retrofit system of claim 1, further comprising a positive connection assembly fastened through the bracket and under the rail.
3. The retrofit system of claim 1, wherein the positive connection assembly comprises a nut and bolt assembly.
4. The retrofit system of claim 1, wherein the bracket comprises a first member and a second member that together form a U-shape.
5. The retrofit system of claim 1, further comprising a top tread configured for disposal between a landing and the stairs to visually obstruct the support angle.
6. The retrofit system of claim 5, wherein the top tread is configured to cover one or more gaps disposed between the stairs and the landing such that a continuous surface is created.
7. The retrofit system of claim 1, wherein the support angle is connected to the stairs with a mechanically fastened connection, a bolted connection, an extruded complete component, or a welded connection.
8. The retrofit system of claim 1, wherein the support angle comprises steel, aluminum, or another metal.
9. The retrofit system of claim 1, wherein the bracket is further configured for coupling with a side stringer of the stairs.
10. The retrofit system of claim 1, further comprising a cover plate configured to cover at least one of a gap or the stair system between the stairs and a landing.
11. The retrofit system of claim 10, wherein the cover plate is further configured to move in any lateral direction in order to provide a continuous, gap-less path.
12. The retrofit system of claim 10, wherein the cover plate comprises a metal sheet or a metal plate.
